wheel,v Rare filled upv (each cell receiving one peg) the wheel turns around in the direc-h tion of the arrow anddrops each peg, in turn, into the tube S Fig. 2. The wheel R is rovided with a ratcheton its outer circumerence, which is operated by a pawl connected with the lever T, and Tis connected with, and set in motion by, a` cam on the Figs. 5,' 6,7 and. 8 are different views of the apparatus connected with the tube S, which composes what): call the detectors and isfexplained as follows, viz: Then the peg `c'omes down the tube S, it may come point downward, or not, just as it happens, and the object of this part of the machine is to set the points of all the pegs in yone direction,`which is effected as follows, viz: U,

Figs'bl and 7 is a short shaft,with a crank Vfat oneend, and the'forceps or clamps at the other. This shaft makes only one fourth of a revolution, alternately, forward 'i and' back, and is operated by the levers X,

X,l which are moved by a cam on the main shaft. hen the levers X turn the shaft U so as to bring the clamp WV into a perpendicular position as seen in Fig. 6, one half of the clamp strikes against the stationary piece Y which causes it to open. The peg now drops from the "tube Q, in between the jaws' of the forceps and is'prevented from dropping farther by the steel plate just beneath. The levers X now turn the forceps, with the peg between them, one fourth turn tora horizontal position. The peg is next operatedy uponby the small wire punches Z, Z,

which aremoved to and fro, by the levers a, d, operated by'a cam on thev main shaft. If one of these'punches Z, strikes the peg on its head it" forces it .from the forceps W, and pushes it point'first through one of the detectors b, b, -into the channel c, c.

The square holel The form. and construction of the detectors b, maybe .better seen in Figs. 6, 7, and 8, Fig. 8, shows a .front of one of the detectors, which, as is indicated is made in two parallel pieces which are kept pressed at the 'bottomis where the peg enters; the

edges of this hole at its entrance are beveled or chamfered so that the point of the peg may enterreadily. If the point of the peg c'ome's'first, it presses the two parts asunder and the' peg is forced through, but if one of the .punches Zshould strike on the point ofthev peg, the head would be forced against the detector, and the hole not being large enough to admit it, the vpeg would not entenl but would remain in the forceps W, until, the other vpunch came and forced it point first, intofand through the opposite detector. A' VVhen'Jthe iirst punch strikes on thelpointy of. peg, the levera, that operates it.- bei' ng. 1dependent for. itsract-ion upon the face-vof a spiral'spring gives way and does not push nthe peg out of the forceps W, butthe other punch is operated by the cam and lever, and when it vcomes up pushes the peg into the channel as aforesaid. The ends of thepunches Z rZ have holes of a conical shape drilled in them, so that when they strike the point of a` pegthey will not batter it up as they otherwise would do. X, X, are little pawls which are so shaped and arranged as to directthe pointfof the peg downward as it enters"V the channel; they are soarranged that thepunches raise them as they .pass'through, and when they- This wheel rests `upon l andQ, which levers are moved by a cam Y on the main shaft.v

I may vary the construct-ion of the wheel al, so that instead of a circular rimy provided with arms and drilled with a series of holes,.I may have spokes or arms merely, with holes or cells at their extremity. a. small punchrthat is operated by the levers z', y', whichv are moved by a cam on themain shaft. The punch 71` playsthrough a hole in the circular plateg, Aand every time the ratchet moves the perforated wheel d, so as tobring a peg over this hole,the .punch pushes it up between the forceps lo, and then withdraws toV allow the, wheel to pass on again. We have ynow brought the peg into a position readyv for use.

The awl and hammer are both mounted on the same carriage with the forceps 70,

and: all swing together about thev post Z."

This carriage is swungback'a-nd forth by the levers m, m, operated by the camY ffon" i the main shaft. The rod n, having the awl in its lower end, is first brought under the maulpor hammerv o, and by thema-ul. is

The forceps are kept in contact with each other by springs pressing against their `sides in opposition to each other. t, t, are levers worked by the cam a, on `the main shaft, and are attached bya` collar around the lower end of the rod a, andwhile the awl is in the" shoe or other piece of leather the cam u., operates theflevers t, t, so as `to cause the shoe to move along the same distance the egs are to be apart; (and this distance can e regulated by the set screw 1),) when this is done, the awl is Withdrawn, and as soon as it is withdrawn, a spring jw, brings it back to its former position ready to` be driven again. The maul o, is driven similar to a trip hammer by cams on the main shaft, and strikes twice to one revolution of the shaft. A spiral spring m, attached to the end of a belt y, which is partly wound around the axis .a of the maul, assists in giv ing force to the blow.

A', Figs. 1, 2, 3 and l1 is a circular ring having a ring B', projecting from its inner surface.

C' is a plate, supported by the ring B', It carries the clamps D', D', which are intended to hold the shoe last lirmly, while the pegs are being driven in; they are clothed with leather or other elastic material to prevent injury to the shoe.

P' is a pin that is intended to enter the heel of the last, and secure it from moving in its seat. The clamps D', D', are brought to bear against the sides of the last, by means of the levers E', E', the lower ends of which levers are pressed apart by turning up the screw F' which causes the upper ends which are wedge shaped) to enter between the clamps and press them against This arrangement holds the shoe firmly to the plate C', but in order that every point in the edge of the sole may be brought under the awl, the plate C' is made so as to turn easily in the ring B'.

G', is a gage, one end of which is hung on a joint H', the other end of which rests on and against the edge of the sole; of the boot or shoe; being pressed against the gage by the hands of the operator, and turned by the hand in such a position as will keep the edge of the sole at right angles with the gage during the operation of pegging the boot or shoe, the pegs are all driven exactly the same distance from the edge of the sole. The spiral grooves in the end of the gage G' are made so as to Prevent any tendency of the gage to slip from the edge of the sole as theshoe is turned around.

v I I' are four hinge joints of cast iron;

theyrest upon the'levers J', J', and form a seat forthe apparatus that holds the shoe. The ring A' rests upon points on the' four `hinge joints and is attached to each one of them by means of the four spiral springs, N, N. The whole arrangement forms a speciesof universal joint and is so constructed as to enable the operator to give various inclinations to the sole of the shoe, for as the awl only works in a perpendicular direction, it is necessary to change the position of the shoe, so as always to keep that portion of t-he surface of the shoe into which the pegs are being driven at right angles with the awl.

K, is asquaring shaft, having attached the levers L', L'. Rods M', M', connect the tops of these levers with each of the two sets of hinge joints, and thus serve to give a parallel motion to them. The tops of the levers J' are connected by the bar o' so that. the action of the two sets of hinge vjoints may be simultaneous; that is, when we wish to elevate one set of hinge joints by raising the levers that support them, the levers that support the opposite set will be depressed in proportion.

The drawings are made one half the size of a working machine, excepting that part which holds and adjusts the shoe, which is only one tenth size; and was so drawn for the sake of making the drawings more compact.
